SPECIFICATION forming part of Iietters Patent No. 506,140, dated October 3, 1 893.

Application filed December 12, 1892. Serial No. 454,831. (No model.)

To all whom it may concern:

Be it known that I, CYRUS A. TAFT, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Separators for Spinning-Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in the mechanism by which the yarn separators of spinning-machines are operated and controlled.

The object of this invention is to provide a separator operating mechanism bywhich the movements of the separators are positively controlled both on the upward and downward movement of the ring-rail.

Another object of the invention is to produce a separator operating device which will control the action of the separators for the full movement of the ring-rail and operate the separators on the back and forward stroke during the upper traverse of the ring-rail.

Still another object of the invention is to produce a positive operating-mechanism for yarn separators from which the separators may be readily disconnected when it is desired to throw the same upward by hand.

The invention consists in the peculiar con struction of the mechanism operated by the upward movement of the ring-rail to control the upward and downward throw of the separators.

The invention also consists in the combination with the separator operating-mechanism of a clutch adapted to connect two of the parts thereof and to allow of their ready dis: connection. a

Figure 1 represents a front view of portions of a spinning-machine showing the improved separator operating device. Fig. 2 represents an end view of the same. Fig. 3 represents a top View of a portion of the separatorshaft and the separator secured thereto and connected with the controlling-rod by a clutch. Fig. 4 represents a similar View showing a modified form of the clutch. Fig. 5 represents still another modification thereof. Fig. 6 is a sectional view of the separator-shaft to more clearly show the construction, indicated in Fig. 4, for operating the same in lieu of the clutch. Fig.7 represents a top view of the separator and shaft showing a frictionclutch connection, one of the parts of which has a friction sleeve engaging in the frictioncavity of the other part.

Similar numbers of reference designate corresponding parts throughout.

In yarn-separators as heretofore constructed, the actuating-mechanism has been so arranged as to throw the separators upward as the ring-rail ascends, being operated either by mechanism connected with the ring-rail, or working independent of the same. As the ring-rail descends the separators are dropped back to the horizontal position by their own weight, this construction being necessary from the fact that the separators must, at times, be lifted by hand, which would prevent the use of a rigid operating-device. Where a counter-weight is used to balance the separators, the separators are apt to remain in the vertical position as is also the case when foreign substances become lodged in the bearings of the separator shaft. This invention is designed to overcome these and similar defects and to provide a positive upward and downward movement of the separators and at the same time allow of their beactuating-mechanism.

In the drawings 10 indicates part of'the end frame of aspinning-machine, 11 the lower side-rail, 12 the bolster-rail, 13 the ring-rail, 14 the spindle, 15 the top-rail, 16 the separafiat surface against which the fiat surface of the separator-sockets are pressed by the setof the separators. 18 is the rock-shaft on which an arm 19 is secured, the outer end of this arm being connected by the rod 20 with the ring-rail, so that, by the rocking of the shaft 18, the ring-rail is raised and lowered. The actuating-mechanism consisting of the rock-shaft 18 and the mechanism intermediate this shaft and the separator-blades is driven in anyusual manner. This drivingdevice is, therefore, not illustrated herein as any of the well-known devices may be used.

ing moved by hand without reference to the tors, 17 the separator-shaft having an outer,

screws to prevent the independent rotation Ice To the rock-shaft 18 the segmental-plate 21 is secured, this plate having a curved bearing-surface and the slots 22-22. The camplate 23 has the cam-groove 24 formed in one surface and has the lugs 25--25 by which it is secured to the plate 21 by bolts 26 passing through the slots 22.

The bracket 27 is secured to the lower facerail 11, and pivoted to this bracket is an arm 28 having at one end aroller-bearin g 29 which is engaged in the cam-groove 24 of the plate 23, the opposite end of the arm 28 being furnished with a slot in which the lower end of the actuating-rod 30 is adjustably clamped, the upper end of this rod being pivoted to a crank-arm of the separator-rod. The camgroove 24 may extend through the plate 23 in the form of a slot. It is obvious that when the ring-rail is reciprocating at its lower traverse the actuating-rod will notbe operated in either direction, the roller-bearing being then in the lower portion of the camgroove 24: and moving in a circle concentric to the rock-shaft. As,however, the ring-rail reaches the center of its upward traverse the roller-bearing begins to ride up over the shoulder of the cam-groove and is lifted thereby, thus depressing the opposite end of the arm 28 and actuating the separator-shaft through the rod 30 to lift the separators. On the downward movement of the ring-rail this operation is reversed and the separators are operated by a positive connection and brought to the horizontal position between the spindles.

As it becomes necessary from time to time to lift the separators from between the spindles without lifting the ring-rail, it is evident that the use of rigid connections between the rock-shaft 18 and the separatorshaft would not be practical. To overcome this difficulty I construct the sleeve for securing the crank-arm 33 to the separator-shaft in the form of a clutch of which several modifications are shown in the drawings. Then the clutch is secured to the separator-shaft the separator is generally formed in part with one portion 34 which also serves as an eye to secure the separator to its shaft. On one side surface of this eye is formed one or more teeth or projections 35 adapted to be engaged by cavities or projections 36 of a longitudinally-movable sleeve 37 on which the crank-arm 33 is secured. These latter sleeves are generally pressed against the separator-eyes by coiled springs 38 which surround the shaft 17 and are held by stop-collars 39.

The clutch may sometimes be formed in part with a sleeve 40, shown in Figs. 4 and 6, which has no connection with the separators, and the coiled-spring, for forcing the parts of the clutch together may be mounted on the pivot on which the movable part of the clutch is carried.

The peculiar construction of the arm 33 shown in Figs. 4 and 6, may be applied to the arm 28 and a rigid-arm used on the separator-shaft. In this construction the separators may be perfectly balanced by the counterweights 17 on the rock shaft, and this is particularly desirable as it reduces the necessary pressure between the parts of the clutch or separable connection, very little power being required to move the counterbalanced separators.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. In a spinning machine, the combination with the separators and the actuating-mechanism thereof, of a separable clutch-connection forming part of such mechanism and adapted to be operated by the movement of the separators against the resistance of the driving-mechanism.

2. In separators for spinning-machines, the combination with the separators, of an actuating mechanism, and a clutch included in such mechanism, interposed between the separators and the driving device.

3. In a spinning machine, the combination with a shaft, the separators mounted thereon mechanism for partially rotating said shaft and a clutch connecting the mechanism and the shaft, of a rock-shaft, and a cam having upper and lower bearing surfaces adapted to engage abearing on said shaft-rotating mechanism.

4. In a separator mechanism, in combination, the shaft, the separators suitably mounted on said shaft, actuating mechanism for partially rotating the shaft, means carried by a rock-shaft for operating said actuatingmechanism and a two part clutch forming a separable connection between the rock-shaft and the separators.

5. In a separator mechanism, in combination, the rock-shaft 18 and means for rocking the same, the plate 21 carried by the rockshaft, a plate having the cam-groove 2 L secured to said plate 21, a pivoted arm having a roller-bearing engaged in the cam-groove, a separator-shafta rod connecting said arm with an ofiset arm on the said separatorshaft and a friction clutch interposed between the rock-shaft and the separator-shaft.

6. In a separator mechanism, the combination with the separators, the separator-shaft suitably journaled, and a two-part springclutch secured tosaid shaft and having an oifset-arm, of actuating-mechanism connected with said arm for partially rotating the separator-shaft.

In witness whereof I have hereunto set my hand.
